12VDC and 24VDC (9.5VDC-34VDC) to 8V DC/DC converter
These are efficient switching DC converters, designed to allow the use of 8 volt video cameras with 12 volt batteries. The input voltage can be anywhere between 10 volts and 34 volts. These 8V output converters have been designed to be very rugged electrically and can be operated continuously over a wide temperature range -40°C to 75°C (65°C for the 5A version).
These are also known as 8 volt voltage reducers, and voltage regulators.
Custom output voltages are available from 3.3VDC to the input voltage minus 1.5 volts (10.5VDC for a 12 volt input, 22.5 for a 24 volt input)
Note 1: Extended operation at voltages less than 8.0 VDC is not recommended although the unit will work at voltages lower than this with reduced load regulation. With voltages lower than 7.0 VDC, output voltage will drop out until the voltage is increased.
Note 2: If an overload is sensed, the unit will automatically limit the output current and reduce the output voltage. If the output voltage is excessively reduced to limit current, the unit will go into a hiccup mode and wait until the overload is removed to restore power. This dual-mode overload protection system allows the unit to be protected from continuous short circuit connection and other overload conditions.
Note 3: Extended operation at temperatures above 75°C can damage the unit and will void the warranty.
Note 4: If the in-line 4A fast-acting fuse is not connected as shown in Figure 2, a reverse polarity connection can damage the unit and will void the warranty.
